Summary of the invention
Problem to be solved by this invention
In this dual-layer type disc, usually at first, with data recording in the L0 layer.With after data recording is in whole L0 layer, with data recording in the L1 layer.Therefore, have such situation, be about to data recording in whole L0 layer, simultaneously only with data recording in the part of L1 layer.If carrying out finalization processing under this situation can on existing cd-rom player, existing DVD-ROM player or the like, the data on the CD being reset, so must be in the L1 layer that does not record data with pseudo-data recording.Therefore, have such technical matters, promptly compare with the size of data that in fact writes down, it need spend more time to carry out finalization processing.
Therefore, can expect a kind of like this recording method, this recording method alternately records recorded information in L0 layer and the L1 layer (perhaps so that the size of data that records the recorded information in each layer homogeneous) basically.Yet, adopting this recording method, can cause must be during recording operation record object or target to be become the L1 layer or store from the point (i.e. layer jump) that the L1 layer becomes the L0 layer from the L0 layer.Especially, if carry out finalization yet, disk drives or come the principal computer of record data to store so to layer jump by the use disk drives.If layer jump do not stored, can cause so to be difficult to or the impossible such technical matters of the data of reading and recording on CD.
Therefore, for example, if disk drives is stored layer jump, so when data are write down, the records management information that must manage the record that is used for data rewrites.Yet, owing to be used for records management information is recorded in the restriction of the size of recording areas wherein, therefore be exactly only records management information to be rewritten approximately hundreds of times on the DVD of a specific example of CD shortly.I.e. execution level jump continually consequently, has such technical matters, if can not continue recorded information is carried out record so.
On the other hand, if principal computer is stored layer jump, it usually layer jump is provided on the storer that provides for principal computer so.Yet if ejected CD, so also deletion is stored in the layer jump on the storer.Consequently, there is such technical matters, promptly can not be to CD or can not reset to the data that are recorded on the CD with data recording.
Therefore one object of the present invention just provides and a kind ofly recorded information can be recorded better information recording carrier, information record carrier and the method on the information recording carrier that for example has a plurality of recording layers and make computing machine play the computer program of information record carrier effect.

(embodiment of information recording carrier)
At first, referring to figs. 1 to Fig. 6, the embodiment according to information recording carrier of the present invention is discussed.
At first, with reference to figure 1 (a) and Fig. 1 (b), the basic structure of the CD among the recording medium embodiment of the present invention is discussed.Fig. 1 (a) has provided the basic planimetric map of the basic structure of the CD with a plurality of recording areas among the information recording carrier embodiment of the present invention, and Fig. 1 (b) has provided the schematic cross-sectional view and the recording areas structure corresponding concepts synoptic diagram diametrically of CD.
Shown in Fig. 1 (a) and Fig. 1 (b), CD 100 has the record surface that diameter on the disk main body is approximately 12cm, as DVD.On this record surface, CD 100 is that the center has with center pit 101: Lead-In Area 102 and leading-out zone 118; User data area 105 and 115; And mesozone 109 and 119.After this, for example recording layer or the like is laminated on the transparent substrates 110 of CD 100.In each recording areas of recording layer, be that the center replaces, is scroll or concentric arrangement with center pit 101 such as grooved tracks and the such track of land track.On this track, be that unit comes data are divided and record with the ECC piece.The ECC piece is the Data Management Unit of following pre-format address, and the recorded information in the described pre-format address is that error is correctable.
By the way, the present invention especially is not limited to above-mentioned CD with these three districts.For example, even do not have Lead-In Area 102, leading-out zone 118 or mesozone 109 (119), also can construct following illustrated data structure.In addition, as described later, can further carry out segmentation to Lead-In Area 102, leading-out zone 118 or mesozone 109 (119).
Especially, shown in Fig. 1 (b), CD 100 among this embodiment has such structure, and the L0 layer that has promptly constituted an example of the present invention " first recording layer " is pressed on the transparent substrates 110 layer by layer with the L1 that has constituted an example of the present invention " second recording layer ".This two stratotype CDs 100 are being write down and playback time, which recording layer to have the focal position that downside from Fig. 1 (b) shines the laser LB of upside, carrying out record and playback in L0 layer or the L1 layer according to.Especially, from inboard to the outside record data of L0 layer, and from the outside of L1 layer to inboard record data.In other words, the CD among this embodiment is with corresponding according to the CD of opposite track path mode.Yet,, even also can obtain described subsequently various benefits according to the CD of prograde orbit path mode by the structure of being discussed below adopting.
In addition, the CD 100 among this embodiment has on each inboard of Lead-In Area 102 and leading-out zone 118: PCA (power calibration area) 103 and 113; And RMA (recordng management area) 104 and 114.
PCA 103 and 113 is used to carry out the recording areas that following OPC (best power control) handles, and it promptly is exactly in the process of data recording to the CD 100 laser power of laser LB to be regulated (i.e. calibration) that described OPC handles.The OPC pattern recording in PCA 103 and 113, is little by little changed simultaneously laser power, and the reproduction quality (for example degree of asymmetry or the like) of the OPC pattern that write down is measured, thereby calculate at the optimal laser power that data is carried out in the recording process.
RMA 104 and 114 is used for following various management information are recorded in wherein recording areas, and described management information is used for data recording is managed to CD 100.
In addition, it is the so two-layer one-sided type of double deck type that the CD 100 among this embodiment is not limited to, and can be to be the so two-layer bilateral type of double-deck bilateral type.In addition, the CD 100 among this embodiment is not limited to above-mentioned CD with two recording layers, and can be the multi-layered type CD with three layers or multilayer.
Next, with reference to figure 2, to such one side on the CD 100 of data recording in this embodiment is discussed in more detail.Fig. 2 is from the conceptive explanatory view that has provided data recording such aspect to the CD of this embodiment.
As shown in Figure 2, CD 100 has two recording layers (being L0 layer and L1 layer).The L0 layer has: Lead-In Area 102 and mesozone 109.The L1 layer has: leading-out zone 118 and mesozone 119.In addition, filesystem information 101 is recorded between user data area 105 and the Lead-In Area 102, and filesystem information 111 is recorded between leading-out zone 118 and the user data area 115.After this, in this embodiment, the recording areas that has write down filesystem information 101 and 111 is assigned as R_Zone (record partitioning) #_1.In addition, user data area 105 and 115 is assigned as R_Zone#_2.
Especially, in the CD of this embodiment, there are a plurality of recording sections (specific example in " first zone " of the present invention and " second zone ") in the user data area 105 and 115 in L0 layer and L1 layer respectively.The data field 115a of certain customers, 115b or 115c that each recording section has the data field 105a of certain customers, 105b or 105c and constituted the part of user data area 105 or 115.For example, first recording section has data field 105a of certain customers and the certain customers data field 115a relative with the data field 105a of certain customers.Second recording section has data field 105b of certain customers and the certain customers data field 115b relative with the data field 105b of certain customers.The 3rd recording section has data field 105c of certain customers and the certain customers data field 115c relative with the data field 105c of certain customers.In this case, for example, from irradiation side or the emitting side of laser LB, data field 105a of certain customers and the data field 115a of certain customers have the same position relation.In other words, because CD 100 is according to the opposite track path mode, so the address value of the address value of the data field 105a of certain customers and the data field 115a of certain customers has the complement relation each other.Yet even do not have strict same position relation from the data field 105a of irradiation side certain customers of laser LB and the relative data field 115a of certain customers, they also have basically the position relation that is equal to the same position relation.Perhaps, if they have the position relation that can not influence recording operation and replay operations, allow some deviations or dislocation so more or less.
After this, by being that unit is to carrying out record such as cinematic data and such content-data and other the various data of voice data with the recording section.In other words, for example some cinematic data (or file) are recorded in first recording section.For example, some voice datas (or file) are recorded in second recording section.For example, some data (or file) with PC record in the 3rd recording section.Especially, at first with data recording in first recording section, secondly with data recording in second recording section, and the 3rd with in data recording to the three recording sections.After this, because the CD 100 among this embodiment is according to the opposite track path mode, therefore inner circumferential side to the outer circumferential sides from the L0 layer of each recording section is carried out record to data.On the other hand, from outer circumferential sides to the inner circumferential side of the L1 layer of each recording section data are carried out record.In other words, according to the direction shown in the arrow among Fig. 2 data are carried out record.
In addition, some forms data (file) are recorded on a plurality of recording sections.In other words, can be in whole first recording section with the part of records of forms data, and after this, remaining forms data is recorded at least a portion of second recording section.In brief, in turn from first recording section by being that unit comes data are carried out record with the recording section.
Especially in this embodiment, a plurality of recording sections have identical or essentially identical size.This is discussed in more detail, and the data field 105a of certain customers, 105b and the 105c of the L0 layer in a plurality of recording sections have identical or essentially identical size.In addition, the data field 115a of certain customers, the 115b of the L1 layer in a plurality of recording sections and 115c have identical or essentially identical size.Because the data field 115a of certain customers (or 115b or 115c) of the data field 105a of certain customers (or 105b or 105c) of L0 layer respect to one another and L0 layer has constituted a recording section, therefore the data field 105a of certain customers (or 105b or 105c) of L0 layer respect to one another and the data field 115a of certain customers (or 115b or 115c) of L0 layer have identical or essentially identical size.In other words, carry out the recording layer that is used in record data at regular intervals and become the such layer skip operation of L1 layer from the L0 layer.
The size (be the size of each data field 105a of certain customers, 105b, 105c, 115a, 115b and 115c, and promptly be the interval of execution level skip operation) of each recording section in L0 layer and the L1 layer is recorded among the RMA 104 (or 114) " layer hop interval " with a specific example of " first size information " of the present invention as having constituted and " second size information ".With reference to figure 3, " layer hop interval " discussed in more detail.Fig. 3 is from the conceptive data structure view that includes such as the data structure of the such RMD (record management data) that will record the data the RMA 104 (or 114) of layer hop interval that provided.
As shown in Figure 3, layer hop interval 121 is recorded among the RMA 104 (or 114).For instance, to promptly being exactly that the form of DVD of a specific example of CD 100 is discussed, layer hop interval 121 is recorded in " 14 " in the field 3 that byte location is RMD extremely in the recording areas of " 15 " with the format 4 that is recorded among the RMA 104 (or 114).That is to say, byte location for " 14 " extremely the recording areas of " 15 " constituted the specific example of " size area " of the present invention.
This layer hop interval 121 is that size is the data of 2 bytes, and represents the size (being the interval of execution level skip operation) of each data field 105a of certain customers, 105b, 105c, 115a, 115b and 115c in each recording section.For example, if 121 expressions and 1000 corresponding sizes of ECC piece of layer hop interval, the size of each data field 105a of certain customers, 105b, 105c, 115a, 115b and the 115c in each recording section is 1000 ECC pieces so.After this, execution level skip operation when the data to 1000 ECC pieces write down.
By the way, except layer hop interval 121, the field 3 of RMD has also write down various data.For example, the data that will be used for representing invisible R_Zone numbering are recorded in byte location and are " 0 " recording areas of " 1 " extremely.The data that will be used for representing the first disclosed R_Zone numbering are recorded in byte location and are " 2 " recording areas of " 3 " extremely.The data that will be used for representing the second disclosed R_Zone numbering are recorded in byte location and are " 4 " recording areas of " 5 " extremely.The data that will be used for representing the start sector number of R_Zone#_1 are recorded in byte location and are " 16 " recording areas of " 19 " extremely.The data that will be used for representing the layer jumping address of R_Zone#_1 are recorded in byte location and are " 20 " recording areas of " 23 " extremely.The data that will be used for representing the end sector number of R_Zone#_1 are recorded in byte location and are " 24 " recording areas of " 27 " extremely.The data that will be used for representing the last recording address of R_Zone#_1 are recorded in byte location and are " 28 " recording areas of " 31 " extremely.The data that will be used for representing the start sector number of R_Zone#_2 are recorded in " 32 " recording areas of " 35 " extremely that has byte location.After this, the same with R_Zone#_1, even for R_Zone#_2, the data that are used for presentation layer jumping address, end sector number, last recording address or the like are carried out record.In addition, if having R_Zone#_3, #_4 or the like, so even for R_Zone#_3, #_4 or the like identical data is carried out record.
In addition, guarantee byte location be " 6 " extremely the recording areas of " 13 " be the reserved area that is used in the future carrying out increased functionality.
As mentioned above, with data recording in each of a plurality of recording sections in such structure, can be sequentially data be carried out record from L0 layer and the L1 layer inner circumferential side each.Therefore, there is such advantage, promptly in the finalization processing procedure of CD, can reduces the required time span of this processing relatively.Especially, to after data recording is in whole L0 layer it recorded under the situation of the CD aspect such in the L1 layer, there is such technical matters, promptly with record whole CD on data volume compare, its needs relatively the longer time finally to change, because data are recorded in the whole L0 layer and are difficult to data is recorded in the L1 layer.This is because it needs time span so that pseudo-data recording is not recorded in the zone of data in L1 layer wherein.Yet, according to this embodiment, various data are recorded in each recording section, therefore can be basically equably with data recording in each of L0 layer and L1 layer.Therefore, as mentioned above, will pseudo-data recording in the L1 layer.In other words, on the outer circumferential sides of mesozone 109 and 119, recording status (or mirrored state) is not allowed.Therefore, can reduce the required time span of finalization processing, therefore can help to reduce record operating time and can improve comfortableness of user or the like.
Therefore because each recording section has identical or essentially identical size, described subsequently disk drives and principal computer or the like point (i.e. layer jump) that will not change as the recording layer of record object is stored in wherein, also can identify each recording section.In addition, because each recording section has identical or essentially identical size, therefore be enough to layer hop interval 121 once recorded among the RMA 104 (or 114).In other words, needn't all will carry out record to RMD when changing as the recording layer of record object, this can not cause do not have the such shortcoming in more recordable recordings district outside RMA 104 (114).Therefore, can continue recording operation.
After this, even before finalization processing, ejected CD 100 from disk drives, so even under situation about data alternately being recorded in each recording layer, by the layer hop interval 121 of reference record in RMA 104 (or 114), also can identify the data structure (the particularly structure of each recording section) on the CD 100.That is to say, can obtain the size of each recording section from layer hop interval 121, therefore by carrying out scheduled operation or computing, can be better and relatively easily identify data structure (the particularly structure of each recording section) on the CD 100.
By the way, with reference to figure 4 and Fig. 5, the more detailed data structure of the CD among this embodiment 100 is discussed.Specifically, to discussing by using the marginarium to come that data are write down such aspect.Fig. 4 writes down so that comprise the data structure view of the record aspect that a plurality of recording sections are such marginarium data from conceptive having provided.Fig. 5 writes down so that the data structure view of the relevant such record aspect with marginarium of recording section data from conceptive having provided.
As shown in Figure 4, data are write down so that comprise a plurality of recording sections in a marginarium.For example, in Fig. 4, first marginarium comprises first recording section and second recording section.Second marginarium comprises the 3rd recording section and the 4th recording section.
Now, first and second marginariums are discussed in more detail.First marginarium has: the data field 105a of certain customers, 105b, 115a and 115b; And outer edge area 107a and 117a.In addition, second marginarium has: inner peripheral area 106a and 116b; The data field 105c of certain customers, 105d, 115c and 115d; And outer edge area 107b and 117b.By the way, first marginarium does not have the inner peripheral area as second marginarium; Yet, be included in extra inner peripheral area (or additional boundary district) within Lead-In Area 102 or the leading-out zone 118 have with first marginarium in the inner peripheral area identical functions.By forming this inner peripheral area and outer edge area, can go up at polygon edge ecad information reproducing device (ROM player) or the like the information that is recorded on the CD 100 is reset.
Inner peripheral area 106 and 116 is with being used for the various management information that the data that are recorded in each marginarium manage to be recorded in wherein recording areas, and upwards has the size of for example about some μ m in the footpath of CD 100.
Specifically, physical format information up-to-date or that upgrade is recorded in inner peripheral area 106 and 116.Up-to-date physical format information is represented the distributed intelligence (for example map information or the like) of the data in the respective edges district.Up-to-date physical format information has and 5 corresponding sizes of ECC piece; Yet it is not limited to this.
Outer edge area 107 and 117 is that following various control informations are recorded in wherein zone, described control information be used for being controlled at data recording in the process of each marginarium recording operation and record data are carried out replay operations in the playback procedure, and upwards have the size of for example about 100 μ m to 500 μ m in the footpath of CD 100.
Specifically, RMD copy, stop piece, next edge labelling or the like are recorded in outer edge area 107 and 117.
RMD copy is to be used for the information that the record to data manages and to comprise and the identical information of RMD that is recorded in RMA 104 (or 114).RMD copy can offer the information (being RMD) that is used for the various data that are recorded in the marginarium are reset the information reproducing device (ROM player) of the RMD among the RMA 104 (or 114) that can't read DVD-R for example.
Stop piece comprises that size is the flag information of 2 ECC pieces and whether with data recording to outer edge area 107 (or 117) afterwards represents.That is to say if the information reproducing device that is used for that the data that are recorded on the CD 100 are reset is judged by this stop piece data are not carried out record, it does not read subsequently zone so.
Next edge labelling is to be used for data recording to the employed information of the information record carrier on the CD.For example, by being that 3 data of 2 ECC pieces write down and represent next edge labelling to size.Specifically, if further to outer edge area 107 (or 117) afterwards, so tentation data (for example " 00h ") is recorded as next edge labelling with data recording.On the other hand, if not further to outer edge area 107 (or 117) not afterwards with data recording, next edge labelling is not write down so and the recording areas (specifically, the recording areas of the latter half of outer edge area 107 (or 117)) of outer edge area 107 (or a 117) part is in mirrored state (promptly not recording status).
In addition, as shown in Figure 5, data are write down so that comprise a recording section in a marginarium.For example, in Fig. 5, first marginarium comprises first recording section, and second marginarium comprises second recording section, and the 3rd marginarium comprises the 3rd recording section.First marginarium among Fig. 5, second marginarium and the 3rd marginarium also can have the data structure identical with first and second marginariums shown in Figure 4.In other words, inner peripheral area 106 and 116 and outer edge area 107 and 117 are provided.
By the way, be used for that data recording recording layer is therein become the point of L1 layer from the L0 layer, outer edge area 107 and 117 is arranged in respectively in L0 layer and the L1 layer.By providing outer edge area 107 and 117, can prevent that the optical pickup apparatus that is used for that the booking situation position on the CD 100 is searched for from seeing through (promptly crossing) (perhaps the laser that irradiates from optical pickup apparatus sees through) at this point." see through and " represent such situation here, promptly only provide under the situation of first marginarium at CD 100, when user data area 105a was searched for, the search destination jumped to outside the certain customers data field among the recording areas (for example mirror area) that does not record data.Seeing through of this class optical pickup apparatus can cause subsequently recording operation and replay operations out of control, and this is not preferred.Yet,,, therefore can suitably prevent to see through because outer edge area 107 and 117 are provided according to this embodiment.In addition, by means of outer edge area 107 and 117, can prevent between L0 layer and L1 layer to carry out promptly is exactly to change as in such " layer jumps " process of the change operation of the recording layer of record object since eccentric between the deviation in the taping process or two recording layers or since the deviation of laser irradiating position cause layer jump afterwards laser enter the recording areas that does not record data.
In addition, consider for example off-centre or the like, can be configured to make the size of the size of the data field 105a of certain customers in the L0 layer greater than the data field 115a of certain customers in the L1 layer.Especially, be the size that makes the data field 105a of certain customers in the L0 layer better greater than the size of the data field 115a of certain customers in the L1 layer so that the data field 115a of certain customers in the L1 layer only is arranged on the position relative with the data field 105a of certain customers in the L0 layer.By this, if with data recording in the L1 layer, therefore the laser L0 layer of data that can always shine overwriting can improve recording feature so.Apparently, this is so same for the data field 105b of other certain customers, 105c, 105d, 115b, 115c, 115d or the like.
In addition, as shown in Figure 4 and Figure 5, in aspect coming by the use marginarium data are write down, the R_Zone under the certain customers data field within being included in the affiliated R_Zone in a certain customers data field within the marginarium and being included in another marginarium is different.In other words, in Fig. 4, the data field 105a of certain customers and the 115a that are included within first marginarium belong to R_Zone#_2.The data field 105b of certain customers and the 115b that are included within second marginarium belong to R_Zone#_3.In Fig. 5, the data field 105a of certain customers and the 115a that are included within first marginarium belong to R_Zone#_2.The data field 105b of certain customers and the 115b that are included within second marginarium belong to R_Zone#_3.The data field 105c of certain customers and the 115c that are included within the 3rd marginarium belong to R_Zone#_4.More R_zones is provided on the user data area 105 and 115.Apparently, it is not limited to by using the marginarium to come the aspect that data are write down, but by using more R_Zone to come the aspect that data write down is allowed.With reference to figure 6, the aspect that a plurality of R_Zone are provided is discussed in more detail.Fig. 6 has provided the data structure view of the CD 100a with a plurality of R_Zone on the user data area 105 and 115.
As shown in Figure 6, on user data area 105 and 115, two R_Zone#_2 and R_Zone#_3 have been distributed.In this case, the recording section among the R_Zone#_2 needn't have identical or essentially identical size with recording section among the R_Zone#_3.That is to say that the data field 105a of certain customers (105b, 105c, 115a, 115b or 115c) among the R_Zone#_2 needn't have identical or essentially identical size with the data field 105d of certain customers (105e, 105f, 115d, 115e or 115f) among the R_Zone#_3.Yet first recording section among the R_Zone#_2 has identical or essentially identical size with second recording section.The 3rd recording section among the R_Zone#_3 has identical or essentially identical size with the 4th recording section.That is to say, the data field 105a of certain customers, 105b, 105c, 115a, 115b and 115c among the R_Zone#_2 have identical or essentially identical size, and the data field 105f of certain customers, 105e, 105f, 115d, 115e and 115f among the R_zone#_3 have identical or essentially identical size.
In this case, will record among the RMA 104 (or 114) with the corresponding RMD of R_Zone#_2 and with the corresponding RMD of R_Zone#_3.In other words, will record among the RMA 104 (or 114) with R_Zone#_2 corresponding layer hop interval 121 and with the corresponding layer of R_Zone#_3 hop interval 121.
Even in this structure, can obtain above-mentioned various benefit, because each R_Zone has the structure identical with above-mentioned disc 100.
By the way, the number of the R_Zone on the user data area 105 and 115 be not limited to above-mentioned two or three, and can be more.Even under the sort of situation, for each R_Zone by adopting the structure identical also can obtain above-mentioned various benefit with above-mentioned CD 100.

(2) principle of operation
Next,, to Figure 10 the recording operation of the information recording/playing back device among this embodiment 200 is discussed with reference to figure 8.Fig. 8 is from the process flow diagram of the whole flow process of the conceptive recording operation that has provided the information recording/playing back device 200 this embodiment.Each of Fig. 9 and Figure 10 has provided the data structure view of the process of recording operation.
As shown in Figure 8, at first, CD 100 is loaded into (step S101) on the disk drives 300.At this moment, it can be configured to calculate the optimal laser power that is used for data recording by utilizing PCA 103 (or 113) execution OPC to handle.Perhaps, it can be configured to read and write down necessary various control data to data.
After this, under the control of the CPU359 of a specific example that has constituted " first opertaing device " of the present invention, principal computer 400 logging modes are set to a layer jump logging mode (alternative logging mode) (step S102).Be set to a layer jump logging mode by logging mode, as mentioned above, can be in each recording section with data recording.
After this, principal computer 400 is provided with regard to the recording areas on the CD 100 filesystem information 101 (or 111) is write down (step S103) disclosed R_Zone#_1.
In addition, under the control of CPU 359, with regard to the invisible R_Zone#_2 that next is set to disclosed RJZone#_1,400 pairs of layer hop interval 121 of principal computer are provided with (step S104).For example, be set to layer hop interval 121, by being that unit comes data are write down with execution level and jumps with 1000 ECC pieces by 1000 ECC pieces.In other words, execution level jumps in the time of in the certain customers data field that data is recorded in 1000 ECC pieces.
After this, principal computer 400 to disk drives 300 output orders with in fact with data recording (step S105) to CD 100.
Be exactly under the control of CPU 354 of a specific example of " second opertaing device " of the present invention shortly, the disk drives 300 that is used for receiving this instruction will be used for being illustrated in the structure of the set open R_Zone#_1 of step S103 and invisible R_Zone#_2 or the like information, record among the RMA 104 (or 114) with as RMD (step S106) in set layer hop interval 121 of step S104 or the like.
After this, data are carried out physical record (step S107).In other words, by being that unit comes data are carried out record with the recording section.
For example, as shown in Figure 9, at first, on the direction of the arrow in Fig. 9 with data recording in first recording section.That is to say, data (UD 10) are recorded among the data field 105a of certain customers in first recording section, and after this, data (UD 11) are recorded among the data field 115a of certain customers in first recording section.After this, on the direction of the arrow in Fig. 9 with data recording in second recording section.That is to say that just data (UD 20) record among the data field 105b of certain customers in second recording section, and after this, data (UD21) are recorded among the data field 115b of certain customers in second recording section.In addition, on the direction of the arrow in Fig. 9 with in data recording to the three recording sections.That is to say, data (UD 30) are recorded among the data field 105c of certain customers in the 3rd recording section, and after this, data (UD 31) are recorded among the data field 115c of certain customers in the 3rd recording section.At this moment, the size of each recording section (being the size of each data field 105a of certain customers, 105b, 105c, 115a, 115b and 115c in each recording section) is the represented size of the set layer hop interval of step S104 in Fig. 8 121.In other words, by set each layer hop interval 121 execution levels of the step S104 in Fig. 8 are jumped, by being that unit comes data are carried out record with recording section shown in Figure 9.
In Fig. 8, after data were write down, principal computer 400 was equipped with filesystem information 101 (or 111) (step S108) according to layer hop interval 121 or the like once more.Filesystem information 101 (or 111) comprises and is used to information of representing the data structure (particularly structure of each recording section or the like) on the CD 100 or the like.The filesystem information 101 (or 111) that is equipped with is recorded among the open R_Zone#_1 set in step S102.
After this, principal computer 400 is carried out finalization processing (step S109).Finalization processing is can be by coming such as the such information reproducing device of DVD-ROM player such processing of resetting by the information on the CD of being recorded in such as the such information record carrier of DVD-R/RW register.
Specifically, as shown in figure 10, various essential management information or the like are recorded in Lead-In Area (L1) 102 and the leading-out zone (L0) 118.After this, on the outermost circumference side in the zone of having write down data, be equipped with mesozone 109 and 119.For example with " 00h " data recording in middle 109 and 119.In addition, because data are not recorded in (being to have the recording areas that does not record data among the data field 115c of certain customers) among the entire portion user data area 115c in the 3rd recording section, therefore padding data (PD) are recorded in the recording areas that does not record data.By the way, padding data for example is " 00h " data.Yet if formed some record pits, padding data is not limited thereto so.This is like this equally for " 00h " data that record in the above-mentioned mesozone 109 (or 119).
Here, if with after data recording is in whole L0 layer with data recording in the L1 layer, so must be in the zone that does not record data with pseudo-data recording.This be to keep with such as the so mutually compatible necessary processing of only playback type CD of DVD-ROM.Therefore, suppose that the 5GB data recording is had on the such CD of the recording capacity of 4GB to each of L0 layer and L1 layer, so with the data recording of 4GB in the L0 layer and with the data recording of 1GB in the L1 layer.In this case, must be with in the residue clear area with 3GB of pseudo-data recording in the L1 layer.This can cause the required time span of finalization processing to increase.
Yet, in this embodiment, can be basically equably with data recording in each of L0 layer and L1 layer.In other words, data are write down with until the essentially identical radial position in each of L0 layer and L1 layer.For example, suppose that 5GB data recording each to L0 layer and L1 layer is had on the CD of 4GB recording capacity, so with the data recording of 2.5GB in each of L0 layer and L1 layer.Therefore, will pseudo-data recording in recording areas not, and as mentioned above, be enough in having write down the outermost circumference district of data, be equipped with the mesozone.Therefore, existence can reduce the so very big benefit of the required time span of finalization processing.
Because each recording section has identical or essentially identical size,, also can identify each recording section even disk drives 300 and principal computer 400 point (i.e. layer jump) that will not change as the recording layer of record object is stored in wherein so.In addition, because each recording section has identical or essentially identical size, therefore be enough to once layer hop interval 121 be recorded among the RMA 104 (or 114).In other words, needn't all will carry out record to RMD when changing as the recording layer of record object, this can not cause do not have the such shortcoming in more recordable recordings district outside RMA 104 (or 114).Therefore, can continue recording operation.
After this, even before finalization processing, ejected CD 100 from disk drives 300, so even under situation about data alternately being recorded in each recording layer, by the layer hop interval 121 of reference record in RMA 104 (or 114), also can identify the data structure (the particularly structure of each recording section) on the CD 100 better.That is to say, can obtain the size of each recording section from layer hop interval 121, therefore by principal computer 400 (or disk drives 300) is carried out scheduled operation or computing, can be better and relatively easily identify data structure (the particularly structure of each recording section) on the CD 100.
In addition, to aforesaid data recording is discussed briefly to the method in the identical or basic identical recording section (being fixed length size).In this case, whether the judgement size of data that will will write down in recording operation is greater than the size of recording section.
As the result of this judgement, if it is bigger to judge the size of this recording section, the data recording that will write down is in the part of recording section so.
On the other hand, if it is bigger to judge the data that will write down, the part of records of the data that will write down is in a whole recording section so.After this, the remaining data that will write down that writes down is not yet recorded in the part of another recording section.More particularly, be 15MB if the size of each recording section is the size of the 10MB and the data that will write down, so in data recording to a recording section with 10MB, and with the 5MB data recording in another recording section.Apparently, want big data carry out record if contrast total size of two recording sections, so with the part of records of data in all recording sections and other part, and in addition, remaining data is recorded in another recording section.
In addition, as in Fig. 4 and Fig. 5, discussing,, when data recording is finished, carry out the edge so and close processing in each marginarium if be the marginarium with data recording.In other words, inner peripheral area 106 and 116 and outer edge area 107 and 117 have been formed.If with various management information or the like be recorded in inner peripheral area 106 and 116 and outer edge area 107 and 117 in, can on the DVD-ROM player of the polygon edge structure that can discern CD, carry out playback so.
In addition, in the above-described embodiments, the example of CD 100 as information recording carrier is illustrated, and the example of the register relevant with this CD 100 as information record carrier is illustrated.Yet, the present invention be not limited to this CD with and register, and the information recording carrier that can be applicable to other various high density recordings or high transfer rate with and register.
The present invention is not limited to the foregoing description, and under the situation of essence of being deduced out in not breaking away from accessory rights requirement and whole instructions if desired of the present invention or spirit, can make various variations to it.The computer program that all relates to information recording carrier, information record carrier and the method for this variation and be used for record controls also belongs within the technical scope of the present invention.
